ABSTRACT:
To improve the speed and simplicity of adjustment of mechanical devices, for example passenger seats and other movable members in motor vehicles, there is provided a closed-loop control system in which servo-motors adjust the final positions of the movable members. The desired configurations, i.e. the positions of the individual members of the device are stored in one or more memories for recall upon the actuation of push-buttons. The same push-buttons are used alone or in conjunction with a data storage switch to store new positions in the memory. The servo-motors are coupled to transducers which generate an electrical signal related to the position of the servo-motors and their associated movable members. Upon actuation of one of the push-buttons, the device is adjusted until the control deviation is near-zero, i.e. until the signal from the transducers conforms to the data stored in the memory.
